GDT did not say flatly 'no -not in 3D' as some posters have correctly pointed out. But if shooting is to start in 7 months time how could conversations not be taking place if it is being shot in 3D - GDT categorically said they are not. So we have a riddle.

If the technology exists for a 2D to 3D conversion (which it does) and if 3D is taking off would it not make marketing sense for a later re-release of the Trilogy to include showings in 3D - to give fresh experience to the huge mainstream audience and entice them to take a look? If so then converted 3D Hobbit films would be logical for a (then) consistent experience.

GDT may just be leaving the door ajar for 3D Hobbit versions at that point - with no current intention to release it only or originally in 3D.
